Do you want to build it? (My answer)
If you have two weeks to a project you should do it easily. It isn't expensive except 'some of the coils and magnets'...But if you have 1 week to the project I prefer a partnership to create it or it would be a too big project in these few hours you have. Except you'll use all your spare time.
A good advice.
Handle the project gently!
You have to know. More closely the coils are to the magnets make the generator much more electricity!
Please give some good feedback which can make the whole generator more useful.
Enjoy the video - If you have any question just write them in the description.(I'll try to answer within 24hours)
(I'll also thank Kirstine. She and her clever brain did a lot of hard work! It wouldn't be this wonder if I wasn't in a partnership with her. )
